How Much Oil Does a Lawn mower Take? Every Thing You Need To Know

Picture this: it’s a sunny Saturday morning, and you’re ready to tackle that overgrown jungle you used to call a lawn. You grab your trusty lawn mower, pull the starter cord, and with a satisfying roar, it springs to life. As you push it across the grass, you can’t help but wonder, “How much oil does this thing actually need?” It’s a question that may have crossed the minds of many weekend warriors like yourself. Well, fear not! In this article, we’re diving deep into the fascinating world of lawn mowers and uncovering the answer to that burning question: just how much oil does a lawn mower take? So, buckle up, garden enthusiasts, as we embark on a journey to demystify this small yet essential component that keeps our lawns looking trim and pristine.

Remember that oil requirements vary significantly from one lawn mower to another, with typical capacity ranging from 15 to 70 oz. For example, walk-behind mowers, like those from Briggs & Stratton, generally require between 48oz and 64oz of oil, while different models and brands may have varying amounts. Always use the correct type and amount of oil for your mower’s engine based on the operator’s manual to avoid potential damage or performance issues.

Types of Lawn mowers and Oil Requirements

Gas-Powered Lawn mowers

The type and amount of oil required for gas-powered lawn mowers can vary depending on the engine and climate. Typically, engines need either SAE 30 or SAE 10W-30 oil, which have temperature-dependent qualities. Synthetic SAE 5W-30 oil can also be used, as it provides the best protection in all temperatures and improves starting with less oil consumption.

The oil capacity for gas-powered lawn mowers can range from 15 to 70 oz, with variables such as engine size and power playing a role. Similarly, oil change intervals can vary from every 50 hours of operation or every year for walk-behind lawnmowers to every 100 hours for riding mowers.

Electric Lawn mowers

Since electric lawnmowers don’t rely on an internal combustion engine, their oil requirements differ from those of gas-powered mowers. They typically do not require oil in the same sense, instead using grease or lubricants for the motor and other moving parts (if needed).

Remember to consult your lawn mower’s owner’s manual, as the specific type and amount of lubrication might vary according to its make and model. Properly maintaining your electric lawn mower ensures long life and excellent performance.

Determining Lawn mower Oil Capacity

When it comes to determining the oil capacity of your lawn mower, there are a few reliable methods to help you find the correct amount.

Owner’s Manual

First and foremost, consult the owner’s manual that came with your lawn mower. This valuable resource will typically provide the exact oil capacity for your specific model and the recommended type of oil to use. If the manual is unavailable, search for a digital copy online by entering your lawn mower’s make and model number.

Walk-behind or push lawn mowers with small engines have oil capacities ranging from 15 to 24 oz, while riding lawn mowers take 48 to 64 oz. of engine oil. However, these values may vary, so always refer to your manual.

Manufacturer’s Website

If you still need help finding the necessary information in the owner’s manual, visit the manufacturer’s website. Search for your lawn mower’s make and model number, and look for an online support section or frequently asked questions page. This should provide you with the oil capacity and recommended oil type. If you still have questions, contact the manufacturer’s customer support team for assistance.

Remember to consider different oil types, such as SAE 30, SAE 10W-30, and Synthetic SAE 5W-30, as the oil you use may greatly depend on your climate.

Choosing the Right Oil

Oil Types for Different Weather Conditions

When selecting oil for your lawn mower, it’s essential to choose the right type based on the climate in which you live. For hotter environments, you should use an oil designed to work in high temperatures. On the other hand, if you live in colder climates, you must opt for an oil that can efficiently work in cool temperatures 1. Using appropriate oil will help ensure the proper functioning and longevity of your lawn mower engine.

Oil Viscosity

Oil viscosity refers to the thickness of the oil, which affects how well it will flow and coat the internal components of your lawn mower’s engine. Generally, lower viscosity oils (such as 10W-30) are suitable for colder climates, while higher viscosity oils (like SAE 30) are ideal for warmer environments2. The manufacturer of your lawn mower will usually specify the recommended oil viscosity in the owner’s manual, so be sure to consult that before making a decision. Remember that always using the correct viscosity oil will help protect and extend the life of your lawn mower engine.

Checking and Changing Lawn mower Oil

When to Check

It’s essential to regularly check your lawn mower’s oil levels to ensure optimal performance and engine health. Most grass mowers require an oil change after every 20 to 50 hours of operation. However, this depends on your lawn mower’s type, model, and engine. You should change the oil for a new lawn mower engine after the first five hours of operation. Additionally, checking the oil every time you use it is a good practice.

How to Check Lawn mower Oil?

To check the oil level in your lawn mower, follow these steps:

  1. Turn off the engine and let it cool down if you’ve been using it recently.
  2. Locate the dipstick or oil filler cap, usually found on the top or side of the engine.
  3. Clean any debris around the dipstick or cap before removing it to prevent dirt from entering the oil tank.
  4. Remove the dipstick and wipe it clean with a lint-free cloth or paper towel.
  5. Reinsert the dipstick at the correct angle.
  6. Remove the dipstick again, and observe the two notches. If the oil level falls between them, your lawn mower has enough oil. However, if the level is below the first notch, add more oil to the hole where you removed the dipstick.

Note: Use only the type of oil recommended by your lawnmower’s manufacturer.

How to Change Lawn mower Oil?

Changing your lawn mower’s oil requires a few simple steps:

  1. Warm up the engine by running it for a few minutes. This makes the oil easier to drain.
  2. Please turn off the engine and disconnect the spark plug wire to ensure the lawnmower doesn’t accidentally start while working on it.
  3. Place a drain pan or container under the oil drain plug, usually at the engine’s base.
  4. Remove the drain plug and let the old oil drain into the pan.
  5. Once all the oil has been drained, replace the drain plug, and tighten it securely.
  6. Remove the oil fill cap or dipstick.
  7. Add the recommended oil for your lawn mower, being careful not to overfill it. The oil capacity of push mowers ranges between 13-1/2 and 22 ounces while riding mowers require between 48 and 64 ounces.
  8. Replace the oil fill cap or dipstick and reconnect the spark plug wire.
  9. Dispose of the used oil responsibly by finding an approved recycling center or waste disposal site.

Regularly checking and changing your lawn mower’s oil, you’ll help ensure its longevity and optimal performance.


Now that we’ve uncovered the mystery of how much oil your lawnmower needs, you can mow your lawn with confidence, knowing that you have the perfect recipe for a well-oiled machine. Remember, keeping your lawnmower properly lubricated is like giving it a soothing spa treatment.

It not only prolongs its life but also ensures it runs smoothly, allowing you to conquer those unruly blades of grass with ease. So, next time you hear the roar of your lawnmower, take a moment to appreciate the humble oil that keeps it going strong.

And as you bask in the glory of your freshly trimmed lawn, give yourself a pat on the back—you’ve become a true lawnmower aficionado! Happy mowing, my fellow grass warriors, and may your lawnmowers always be well-oiled and ready for action!
